Hi @m.cecere ,

I'm assuming that when you mean it doesn't work, you mean that your apps are not populating on the page. 

Try these following steps:

• Clear your cache and see if you still have the same issue.
• Clear your plugin cache - clear confluence plugin cache

Thanks,

Ben

Hi Ben,
I mean I cannot see the "Upload new app" button and I cannot see two custom plugins installed.
I cleared the cache but nothing changed.

Hi @m.cecere ,

Did you follow the 2nd bullet point as well?

If you still seeing issue after the restart, then would suggest to contact Atlassian Support. 

Thanks,

Ben

[m.cecere]

Yes, I follow both steps but nothing changed. Every call that Confluence makes to pages, spaces, custom apps ecc... goes to 404.

[Benjamin]

That's strange. Recommend retracing all your steps you did for the upgrade. Make sure nothing was accidentally miss. Keep in mind that when you upgrade, customize files do not get carried over.

If still have issue, would suggest contact Atlassian Support.

thanks,

Ben
